That's not fully true. Lots of things get to Europe later (Gemini memories, though we have them now, Spark as latest noteworthy)
Or never. Like the majority of Pixel 10 on device AI features (image editing, magic cue).
I have the AI image editing features on Pixel in Europe.
Some features don't land in Europe because US companies can't handle the amount of languages. For them it is English and maybe Spanish or Chinese because they don't care how heybmake money.
